My tool read the `compile_commands.json` generated by cmake and pass all arguments (except the compiler and the module). So it supposes to run the same as it was by clang... And this is not happen with any modules, it compiles all LLVM code and the majority of Clang.<br>

</div>The "c-index-test" tool can be used to test libclang on a source file, e.g<br>
c-index-test -test-load-source all <arguments><br>
will parse using the given compiler arguments and emit information about the translation unit.<br>
If you can reproduce a crash using some compiler arguments, then you can try creating a preprocessed file and reducing that.<br>
